6 Claims.

This invention relates to new and useful improvements in windows and has especial reference to a storm window which can be easily and quickly reversed for cleaning purposes.

An object of the invention is to provide a storm window sash which can be easily swung out and reversed to clean the normally outside surface without leaning out of the window.

A further object is to provide a simple, rugged, and efiicient structure which can be made of a relatively few simple parts which can be cheaply manufactured and as economically assembled and taken apart as desired.

Further and more specific objects,' features and advantages will more clearly appear from a consideration of the detailed specification hereinafter set forth, especially when taken in connection with the accompanying drawing which illustrates a present preferred form which the in- Vention may assume and which forms part of the specification.

In brief and general terms, the invention concerns the provision of a window sash, preferably a storm window sash, provided with a channel member across the same in which are disposed rollers supported from one hinge element, the other element of which is fixed in the window sash frame so that the window sash may be swung out and then moved laterally to present the opposite face across the window opening for cleaning.

Preferably there are two channels or rails, one at the top, and one at the bottom of the window sash; and two hinges, one at the level of each channel member and so constructed that when the window sash is swung out of its frame it can travel 180 degrees so that it lies parallel but Well spaced from the adjacent building wall and may then be moved laterally to a position across the window opening for cleaning purposes. The movable hinge member and the channel are provided with cooperating stabilizing means so that the window sash will not tend to sag as it is swung back and forth.

The present preferred form which the invention may assume is illustrated in the drawings, of which, 7

Fig. 1 is an elevation of the storm window sash showing in dotted lines its position when swung out to be reversed;

Fig. 2 is a horizontal cross section taken on the line 22 of Fig. 1;

Fig. 3 is an elevation of the lower right hand corner of the window sash in closed position;

Fig. 4 is a horizontal section taken on the line 44 of Fig. 3;

2 Fig. 5 is a vertical cross section taken on the line 5-5 of Fig. 3; and

Fig. 6 is a partial elevation, partly broken away, of one of the channel rails attached to the frame of the storm window sash.

Referring now merely to the specific form of the invention illustrated herein, it is to be noted that the window opening in the wall H3 is filled by a frame H with a cap piece I2 and sill l3 and an inner trim piece l4. Of course in the frame there is disposed, as usual, an inner window with upper and lower sashes which form no part of this invention and are not shown. The invention relates to the disposition in the outer portion of the frame II of a storm window sash [5 generallyhaving a single intermediate cross piece It with upper and lower glass panes I? and I8 but not having separately movable sashes. This window sash is adapted to be swung out from the position shown in full lines'in Fig. 1 to the dotted position shown in the same figure for purposes of cleaning without the necessity of the person operating it to lean or sit outside of the frame H. To this end the window sash I5 is provided along its top and bottom with cross pieces I9 and 20 with a channel piece having a base plate 2! and top and bottom walls 22, the outer ends of which 23 are bent in spaced but parallel relation to the base plate 21 but which do not quite meet thus forming a slot therebetween. These channel members may be suitably fastened to the cross pieces 19 and 29 by means of suitable fasteners such as screws 2 i. The ends of these channel members are closed by removable end plates 25 suitably and removably disposed in place as shown so that when removed the window sash may he slid off its support as desired.

On a level with these top and bottom channel members are disposed hinges fastened to the sides of the frame H. One of these hinges is shown in detail in Figs. 3, 4, and 5, and it comprises a plate 25 suitably fastened by screws to the inside of one side of the frame II. This hinge plate, which is fixed, is of considerable length so that the hinge axis 21 of it is a desired ample distance beyond the wall In. The movable member of the hinge is a right-angled plate having a portion 28 normally lying parallel and close to the fixed plate 25 and a longer portion 29 lying normally parallel to the adjacent channel member. Mounted on the hinge portion 29 are rollers 39, preferably at least two to each plate 29, and these are rotatably disposed on shafts 3| suitably connected to the plate 29. These rollers are spaced well apart along the hinge plate 29 and project into the channel member so as to provide roller supports along which the channel member and the attached window sash may move. The slot formed between the bent ends 23 of the channel members permit the shafts of the rollers to project into the channel members for-this purpose.

The hinges are so constructed as described that when the hinge is closed as shown in full lines in Fig. 4, the storm window sash is housed snugly within the frame I l but when it is swung out to the dotted position shown in Fig. 1, and parallel to the wall Iii, it is well disposed away from the wall I0. When in this position it is clear that the window sash may then be moved in the direction of the arrow shown in Fig. 2 so as to bring the normally outside portion of the glass therein opposite the window opening whereby it may be cleaned, and the fact that the storm window sash in this position is well spaced from the line of the wall will permit the entire glass surface to be made available for cleaning purposes. In this movement the storm window sash will ride on the rollers which are rotatably mounted on the hinge plates 28.

In order to make the, construction more stable, the channel members, at their ends adjacent the hinges, are provided with apertured lugs 32 to receive the ends 33 of hooks which are pivotally supported on the hinge plates 29 and provided with hand knobs 3 whereby the hooks may be lifted out of the holes in the lugs 32 as desired. This detail of construction will tend to prevent sagging of the sash on the hinges.

In the operation of the device, with the parts assembled and constructed as above described, it is merely necessary to swing the storm window sash out until it is in a position parallel to the wall Ii] as shown in dotted lines in Fig. 2 and then grasp the near side edge in the hand and pull it across the opening whereupon substantially all of the adjacent face of the window sash is available. The ample spacing between the window sash and the wall IE] when the window sash is swung out will permit the portion not directly across the opening to be readily accessible for cleaning. When the cleaning is finished, the window sash is shoved back to the dotted position shown in Fig. 1 and then swung around to the full line position shown in the same figure. In this manner the window sash may be operated for cleaning and the whole operation except for cleaning time is a matter of a few seconds. The parts are simple, rugged, and few in number and can be made cheaply and assembled easily to any type of window with little cost for parts and labor.

While the invention has been described in detail and shown with respect to the accompanying drawing, it is not to be limited to such details, since many changes and modifications may be made in the invention without departing from the spirit and scope thereof. Hence, it is desired to cover any and all forms and modifications of the invention which may come within the language and scope of any one or more of the appended claims.
